Abstract:
M2 acoustic presence of marine mammals and anthropogenic noise manually counted for the period 2019-2020
Quality
Daily acoustic presence of the different sound sources (marine mammals, vessels and airguns) manually identified (except blue and fin whale, automatically detected using spectrogram correlation in Ishmael) during the manual inspection of spectrograms from each acoustic file (one file per hour) for the available data period 2019/2020 in M2, Svalbard. The M2 AURAL recorder sampled 12 min each hour during the given data period.
Variables: dt: date Month: Categorical variable with the name of the month Week: number of week since beginning of the study period Bowhead: acoustic presence of Balaena mysticetus Bowsong: acoustic presence of Balaena mysticetus songs Narwhal: acoustic presence of Monodon monoceros Narwhistle: acoustic presence of Monodon monoceros tonal sounds Walrus: acoustic presence of Odobenus rosmarus Bearded: acoustic presence of Erignathus barbatus Vessel: acoustic presence of vessel noise Odontocete: acoustic presence of odontocete-like whistle and tonal sounds non idetinfied to spp. level Airgun: acoustic presence of airgun blasts Harp: acoustic presence of Pagophilus groenlandicus Humpback: acoustic presence of Megaptera novaeangliae Blue: acoustic presence of Balaenoptera musculus Fin: acoustic presence of Balaenoptera physalus
